This system has now been extended to the first generation iPod touch, bringing all six iPhoneOS models into the Bluetooth arena. Since the 1st gen touch does not provide its own built-in system, it requires an external module. This video uses the dongle described at this blog post to demonstrate the keyboard connection functionality.

Although the 1st generation touch is an increasingly deprecated system, it's nice to know that it hasn't been left out of the Bluetooth picture. Old touch units make excellent hobbyist systems. When jailbroken, access to a full suite of Unix tools offers a budget-priced platform with great prototyping potential. With this new Bluetooth stack support, the 1st gen touch has just become an even more exciting system for projects like remote monitoring.
